ate them. Being impervious to air or water, it may be applied to thesurface of any substance liable to deterioration from dampness,oxidation, 860., and from its antiseptic properties it is peculiarlyadapted to use in rendering tight the joints of cisterns, water-tanks,800.

It is believed thatthis compound possesses many advantages over any inuse intended for a like pur-' pose, among which are, first, while dryingwith equal rapidity, it is more elastic and less liable to crack in coldweather; second, the addition of the mineral in-' gredients renders itless inflammable, and therefore better for roofs or places at all liableto exposure'from fire; third, the ingredients are so cheap and easilycompounded as to render its general use certain.

Having thus fully set forth the nature and merits of my invention,

What I claim as new, and desire to secure by Letters Patent, is-

.A solution of native asphaltum or Cuba bitumen, .combined with mineralingredients and fatty matters, substantially as and for the purposeherein specified.

In testimony that I claim the foregoing, I have here unto set my hand,this 8th day of March, 1869.

To all whom it concern Be it known that LEMILE Vrcron Aumnnnr, of NewOrleans, in the parish of Orleans, and in the State that the followingis a full,vclear, and exact description thereof. I

My invention consists of the production of a waterproof coating,applicable to woods of any kind or to other substances, for the purposeof preserving or rendering them impervious, the component parts of Idissolve native asphal (luba p immenkhappoqpotte) in any cheap ansuitable solvent, such as fredifeii agreement the aide Feat, ifnecessary, and then thicken the-solution with litharge, chalk, or

is ready for use. p

The relative proportion of these ingredients will, necessarily, vary inaccordance with the purpose to which the compound is to be applied,rendering it more or less fluid, or increasing or diminishing itselasticity, as may be desired.

The purposes to which this compound maybe applied Witnesses L. A. LANGE,ALEX. Fuons.
